Pre Composite Floor Load Design Criteria

However if the attic is intended for storage the attic live load or some portion should also be considered for the design of.

Pre composite floor load design criteria.

Analyze composite slab design criteria and calculations to show how a span can be increased and meet strength and deflection requirements without a significant increase to the weight of a slab reference industry standards and discuss how long span steel deck composite floor systems can achieve open. The uniform load moment coefficients assumed in the calcula tions are taken from the a c i. L 480 live load deflection criteria provides a high degree of resistance to floor vibration bounce. Standard 318 71 part 4.

The concen trated load moment coefficients are for the load in the center of the first. 40 psf live load 55 psf total load 85 psf live load 100 psf total load 60 psf live load 75 psf total load. 20 psf uniform load or 150 lb. The building designer desiring this benefit may choose to specify an l 480 live load deflection criteria to be used for the floor trusses.

The dead load on a floor is determined by the materials used in the floor s construction. If one goes down we can replace with a similar pre. Design criteria for composite steel deck same as non composite allowable stress calculated theoretical deflection shall be based on the load of the concrete as determined by the design slab thickness and the load from the steel deck uniformly applied on all the spans and shall be limited to l 180 or inch whichever is smaller. Concentrated load on one foot of deck width.

For better fit and finish our assembled load floors can be formed with. If there s wall board covered ceiling suspended from the underside of that floor the dead load increases to about 10 pounds per square foot. Load and the construction loads specified in the criteria namely. Because the ct systems are going into a variety of different facilities and floor types i would like to specify a maximum floor load such that not only can the facility be prepared accordingly but more importantly to ensure interchangeability among a number of pre qualified ct systems i e.

The success of a concrete slab on a steel frame is more likely to happen when there is coordination between the contractor owner and design team. 2attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes. Meeting oem load specifications our load floor system composite panels reduce overall mass in the cargo system.
